CORPORATION OF ILLINOIS rnnroaa'rme Macrame Application mearbruar 16, 1931; Serial No. 515,919.

The present invention relates generally to.

perforating machines, but more particularly to a type of perforating machine known as the fanfold perforating machine.

One of the objects of the present invention is to provide a novel and improved construction of a removable head for fanfold perforating machines in which the head and the bed, which carry respectively the punches and the die, may be secured together so that both may be mounted on or removed from the main frame of the machine as a unit.

A further object of the invention is to provide a novel and improved form of perforating machine, in whichthe head and the bed may be securely locked together so as to prevent any disalignment from the punches with respect to the die, carried by the head and the bed respectively, so as to prevent any injury or distortion of these parts.

A still further object of the invention is to provide a novel and improved perforating device in whichthe head and the bed may be locked together by certain ofthe driving parts before theremoval from the base or main frame of the machine.

These and other objects are accomplished by providing a construction and an arrange ment of the various parts in the manner hereinafter described and particularly pointed out in the appended claims.

Referring to the drawings.

n fanfold perforating machines which have heretofore been constructed, considerable difficulty has been experienced in maintaining the punches carried by the head in proper alignment with the perforated dies carried bythe bed, and especially in those types of machinesin which the head and bed is separately removable from the machine. Then, too, with this type of machine, considerable time and labor is required as well as many difliculties are encountered inproperly realigning the punches of the head with the die of the bed. g It is therefore, one of the primary objects of the present invention. to overcome these difficulties and provide a novel and improved construction of a perforator head by means of which the head and thebed are locked together as a unit prior to their removal from the main frame of the machine, so that the punches will maintain their alignment with the perforations in the bed. It will also be seen that any number of these removable units of heads and beds may be adjusted on the machine of the unit before they are operatively connected to the driving connections of the perforating machine. I

In illustrating one embodiment of my invention, I have shown the same in connection with the main frameor baseonly a fragmentary portion of which is shown in Fig. lot the drawings and is generally indicatedfby the reference character 10.

Formed integrally with and on the opposite ends ofthe frame 10 and also arranged on theopposite sides thereof, are outwardly extending dovetailed projections or guides 11, which slidingly receive. complementary dovetailed grooved portions 1 2,formed integral-,

1y with the driving bars 13, which are located on the opposite side of the perforating machine. These reciprocating bars 13 are provided on their opposite ends with driving pitman connections 14 which have their upv per ends pivotally connected as shown at 15 to the opposite ends of each of the bars 13 and the lower ends operatively connected to cranks for reciprocating the bars 13. The pitmen 14 are driven through the medium of any suitable transmission in the manner well understood in the art. Extending longitudinally throughout the upper surface of each of the reciprocating bars 13 is a substantially inverted T-shaped recess 16 in which is detachably connected my improved construction of driving connection between the reciprocating head and the driving bar 13. This driving connection may alsobe utilized for positively locking the reciprocating head with its complementary bed, so as to prevent disalignment or injury to the punches or die when they are being removed or adjusted longitudinally of the perforating machine.

My improved removable head and bed construction in which part of the operative connections are utilized for locking the head to the bed so that the same is removable as a unit, comprises a bed 17 which has a portion of its lower surface suitably machined as shown at 18, so that the same may be seated on complementary finished portions 19 of the main frame of the perforating machine. The main frame 10 isprovided with a laterallyrextending projection so as to form shoulders 20 on the opposite sides thereof. Mounted on the downwardly extending portions 21 formed on the opposite ends of the bed 17 are adjustable locking blocks22. The

locking blocks 22 are provided with slotted apertures 23 extending transversely thereof, which are adapted to receive bolts 24 which are mounted in threaded engagement with the downwardly extending portions 21 of the bed 17. The innermost portion of these blocks 22 are adapted to engage the shoulders 20 of the main frame 10 for securely locking the bed to the main frame 10.

- Secured .to the bed 17 by means of cap screws 25 is a die 26 which is provided with a plurality of longitudinally aligned perforations extending vertically therethrough for the accommodation of and cooperation with the punches carried by the head in the manner hereinafter described. Located on the opposite end of the bed 17 and extending up ward therefrom are two shafts or guide rods 27 which are secured to the bed by means of pins 28. Reciprocally mounted on the guide rods or shaft 27 is a reciprocating head generally indicated by the reference character 28. This reciprocating head is provided with two vertically extending bores '29, which reciprocally or slidingly receive the shafts 27 in Vertically guiding the punches through the cooperating perforations formed in the die 26. Founded in the lower portion of the head 28 and secured by means of screws 30 is a punch holding frame, indicated generally by the reference character 31. Mounted in the punch-holding frame 31, is a plurality of spaced apart punches or perforating pins 32 which are adapted to cooperate with the perforations in the die 26 for punching the material passing thereunder. Formed integrally with the head 28 and on the outer ends thereof are outwardly extending portions 33 in which are mounted driving rods 34. The upper ends of these rods 34 are mounted in threaded engagement with portions 33 and are secured against removal therefrom by means of lock nuts 35. The lower ends of the driving rods 34 are provided with round heads as shown at 36 and are adapted'to be seated in the recesses or sockets 37 formed in the lower; end of the driving sleeves generallyindicated by the reference character 38. The driving sleeves 38 have vertical bores 39 therein, so as to permit the sleeves 38to be slidably mounted on the driving rods 34. Formed on the lower portion of the driving sleeve 38 is a non-circular flange generallyindicated by the reference character 39. This flange 39 is larger across one diameter thanit is across'the other di ameter at right angle to. the first, as clearly shown in Fig. 30f the drawings In other words, the upper surface of the flange as indicated at 40 and 41 is adapted to engage the over-hanging shoulder 42 and 43 respectively of the driving bar 13 formed by the inverted T-shaped recess 16. The narrow portion of the flange 39'fas indicated at 44, is of narrower diameter and is capable of being withdrawn from between the inwardly projecting shoulders 45 of the inverted T- shaped recess 16in the reciprocating bars 13. Secured adjacent tothe upper end of the sleeve 38 is a laterally projecting pin 46 which is adapted for engagement with the socket 47 formed in the slidingor locking block-22. The sleeve 38 is locked or securedto the lower end of the driving rod 34 by means of a set screw 48, the inner endof which is adapted to engage aconical recess 49 located in the rod 34 as shown in Fig. 1 of thedrawings; or the sleeve 38 may be locked in the position as shown in Fig. 2 wherein the pin 46 engages the socket 47 in the block 22, in which case the set screw 48 may be secured so that the inner endthereof en ages the conical socket 50 in the dri- 'ng rod 34. 7

The operation of my improvedremovable .unit for perforating machines isas follows:

Let us assume. that the operating parts of both the head. and the bed are in the position disclosed in Fig. 1 of the drawings and that the operator is desirous of removing the head and the bed as a unit from the perforating machine. To perform this operation it is necessary to loosen the bolts24 on the opposite sides of the machine and then by loosening the set screw 48 in each of thesleeves 38, the sleeves may be revolved aquarter of aturn so thatthe narrowportions'44 of the flanges 39 on the sleeves 38 may pass belocking blocks 22. When the sleeves are in this position, the set screws 48 may be tight ened so the inner ends thereof engage the conical recesses 50 in each of the driving rods 34, after which the blocks 22 may be moved outwardly so that the pins 46 engage the sockets 47 in the block 22. After this has been accomplished, the bolts 24 may be tightened and the head 28 as well as the bed 17 will be rigidly locked together so that both may be removed as a unit from the main frame 10 of the perforating machine. In Fig. 2 of the drawings, the head 28 and bed 17 are shown partially removed from the main frame 10, illustrating the manner in which the same may be removed or mounted upon the machine. In this connection, it will also be noted that any number of these heads may be positioned on the machine and ad justed longitudinally thereon, so that the desired distance between the perforations in the paper may be secured.

From the above description, it will be read ily seen that by utilizing the normal driving parts of the head for rigidly locking the head and the bed together as a unit, so that the same may be removed therefrom as a single part, the danger of having the former become disaligned with respect to the die, is entirely overcome. Then too, it will be observed that this construction permits easy and quick replacement of the head, but si mplifies construction and arrangement of parts as to simplify the repair and replacement of the head.

lVhile in the above specification I have described one embodiment in which my invention may assume in practice, it will of course be understood that the same is capable of modification and that modification may be employed Without departing from the spirit and scope of the invention as expressed in the following claims:
